Tubulin.alpha-Tubulin .beta-Tubulin .delta-Tubulin .epsilon-Tubulin .gamma-Tubulin .alpha Tubulin .beta Tubulin .delta Tubulin .epsilon Tubulin .gamma Tubulin .A microtubule subunit protein found in large quantities in mammalian brain. It has also been isolated from SPERM FLAGELLUM; CILIA; and other sources. Structurally, the protein is a dimer with a molecular weight of approximately 120,000 and a sedimentation coefficient of 5.8S. It binds to COLCHICINE; VINCRISTINE; and VINBLASTINE. . 0.83

Lobosea.Tubulinea .A class of amoeboid EUKARYOTES that forms either filiform subpseudopodia or lobopodia. Characteristics include the absence of sorocarps, sporangia, or similar fruiting bodies.
